Even they have a hot spring bath inside of the inn as well. I think they have competitive price for what they offer and much worth than some fancy pricy big inns around this area especially about the meals you get(Well, if you put importance in the view from room, those fancy inns win).
I recommend you to book accommodation with 2meals due to Amanohashidate area hardly have restaurants open during the night and the morning.
This inn located only 2mins walk from Amanohashidate station(天橋立駅).
You can book online from here, Rakuten travel. (in English)
